As illustrated in the picture above, the weatherstripping at the bottom of the sash of this MI Windows 3500 model has degraded and is separating. I am looking for what is the appropriate product name and number to order for replacement. The window sticker is included in the second picture.

I'm afraid that sticker doesn't tell us anything about what weatherstripping is used on this window. This service requires a clear photo of the weatherstripping's end profile in undamaged condition. The video below will clarify what we need.
I know that you said the seal is degraded, but nevertheless the sample you show us must be undamaged. We can't help you otherwise. Please try your best.
